A rotational drive apparatus for screw pilings is described. The apparatus comprises a housing having a cylindrical pipe coupling adapted to receive a shaft of a screw piling therethrough. A detachable connecting element secures the coupling to the shaft at different positions along the shaft. A rotational drive is provided within the housing for imparting rotation to the coupling. An elongated rod is secured to the housing and is held by a user person whereby to immobilize the housing wherein to permit the rotational drive to transmit a drive force to the coupling to rotate the shaft of a screw piling.
